Best Subaru Aftermarket Parts for Repairs and Upgrades

#1 · Best Overall

1. EPAuto Cabin Filter

• Material: Activated Carbon
• Material Type: Activated Carbon

Best for: Carbon cabin-filter replacement.

Why it ranks #1: Activated carbon and soda are listed, with fitment for selected Crosstrek, Forester, Impreza, WRX, WRX STI, and XV models.

Activated carbon containing soda and carbon is the defining feature of EPAuto’s Subaru cabin filter, which the listing says generates a fresh breeze and supports clean air for driver and passengers. Its broad application list covers several older Crosstrek, Forester, Impreza, WRX, and XV model years.

The activated-carbon material and stated soda-and-carbon composition give this replacement a cabin-air focus, while EPAuto also describes it as supporting HVAC performance. Its fit list spans Crosstrek 2016–2017, Forester 2009–2018, Impreza 2008–2016, WRX 2012–2021, WRX STI 2013–2021, XV 2013–2016, and XV Crosstrek 2013–2015. The listing recommends replacement every 12 months or 12,000 miles and notes glove-box access in a four-step replacement process.

Skip it if you need a cabin filter for a Subaru model or year outside the listed applications; this filter’s coverage is specific.

This suits owners of the listed older Subaru applications seeking an activated-carbon cabin filter with a stated annual or 12,000-mile interval. Use the model-by-model year list as the fit boundary before choosing it.

#2 · Best CVT Repair

2. HKSpazz Oil Cooler

• Weight: 1.27 lb

Best for: Listed Subaru CVT cooler replacement.

Why it ranks #2: An aftermarket replacement for OE 31237AA100 covers select CVT-equipped Subaru models, with manual-transmission and other exclusions clearly noted.

This aftermarket transmission oil cooler corresponds to OE reference 31237AA100 and targets selected CVT-equipped Subaru models. Its defined application list spans several Ascent, Crosstrek, Forester, Impreza, Legacy, Outback, and WRX years, while explicitly excluding manual-transmission vehicles and specified exceptions.

The OE reference gives buyers a number to compare against the existing application, while the model list identifies supported CVT-equipped Subaru vehicles. Listed coverage includes Ascent 2019–2025, Crosstrek 2013–2019, Forester 2014–2023, Impreza 2012–2023, Legacy 2015–2025, Outback 2015–2026, and WRX 2015–2025. The exclusions matter: it is not for manual models, WRX STI, or 2022–2023 Forester Wilderness, and fit can vary by trim, transmission configuration, and production date.

Skip it if you have a manual Subaru, WRX STI, or 2022–2023 Forester Wilderness; those applications are explicitly excluded.

For a repair involving a listed CVT-equipped Subaru and OE reference 31237AA100, this cooler provides a defined replacement target. Trim, transmission configuration, and production date can affect fit, and the stated exclusions are firm boundaries.

#3 · Best Legacy Fitment

3. RED WOLF Radio Harness

• Material: Solder
• Weight: 0.03 kg
• Material Type: Solder

Best for: Older Subaru 14-pin stereo wiring.

Why it ranks #3: Its 14-pin adapter connects an aftermarket stereo harness to the factory harness and lists older Impreza, Forester, Legacy, Outback, and WRX applications.

A 14-pin adapter connects an aftermarket stereo harness to the vehicle’s factory harness, making this RED WOLF kit a focused option for listed older Subaru installations. Its compatibility list covers several Impreza, WRX, Forester, Legacy, and Outback applications from the late 1990s through 2008.

The 14-pin adapter provides the stated connection between an aftermarket stereo harness and the factory vehicle harness, supporting a radio replacement workflow without changing the kit’s specified connector role. RED WOLF lists applications including Impreza, WRX, Forester, Legacy, and Outback models, with several individual year and trim exceptions in the compatibility details. The solder material specification is also provided. Because the adapter is specifically 14-pin, that connector format is a key boundary for choosing it.

Skip it if you need an adapter for a different factory connector format; this harness is specifically a 14-pin adapter.

Choose this harness for a listed older Subaru stereo installation that uses the specified 14-pin connection. Its application list spans several models and years, so the connector format and listed vehicle details define the fit.

#4 · Best Tether Repair

4. Click&Fit Fuel Tether

• Material: Plastic
• Material Type: Plastic

Best for: Older-style tether repair.

Why it ranks #4: It restores tethering for several older 42031-series Subaru caps and identifies the matching fuel-door clip, while warning about newer groove styles.

This replacement strap restores the connection between a compatible older-style Subaru fuel cap and the fuel-door tether clip, helping keep the cap from being dropped or left behind during refueling. Its defining fit detail is the external retaining groove used by the 42031SA000-family cap style.

The strap wraps the external retaining groove on the specified older-style cap and anchors to fuel-door tether clip 42037FE060, restoring the cap-to-vehicle connection. The listed compatible cap references include 42031SA000 and several related numbers, so the existing cap style matters. Click&Fit describes tool-free installation, which keeps the repair straightforward without adding a tool step. The listing explicitly distinguishes newer 42031AJ and 42031FJ caps by their different groove profile.

Skip it if you have a newer 42031AJ or 42031FJ cap; its groove profile differs from this strap’s specified older-style fit.

Choose this tether when the existing cap has the older 42031SA000-family groove and the tether has snapped. Its listed anchor is clip 42037FE060; newer cap groove profiles fall outside the stated fit.

5. Subaru Oil Filter Kit

• Material: Metal
• Weight: 0.25 kg
• Material Type: Metal

Best for: Routine Subaru oil-service owners.

Why it ranks #5: The genuine filter includes a crush gasket and lists applications including Ascent, Crosstrek, and four-cylinder Outback and Legacy models.

The genuine Subaru filter-and-crush-washer pairing puts two oil-service components together for owners maintaining supported Subaru models. Its filter is described as removing millions of microscopic pollutants and dust particles, while the included gasket gives you the listed replacement component alongside the filter for a scheduled oil change.

The metal filter and included crush gasket make this a focused service kit rather than a filter alone, keeping both listed components together for an oil change. Subaru identifies fitment for 2019–2026 Ascent, 2013–2026 Crosstrek, and four-cylinder 2013–2026 Outback and Legacy models. The stated filtration of microscopic pollutants and dust particles supports its role in routine engine-oil maintenance. Subaru advises following the owner’s manual, with replacement timing depending on conditions.

Skip it if you own a different engine or model configuration; the listed fitment does not cover every Subaru variant.

For Subaru owners handling routine oil service on a listed model, this pairs the filter with its crush gasket. Check the stated engine and model-year boundaries, especially the four-cylinder restriction for Outback and Legacy.

#6

6. Subaru Cabin Filter

• Material: multi-layer
• Material Type: multi-layer

Best for: Recent Subaru cabin-filter replacement.

Why it ranks #6: This genuine filter lists newer Crosstrek and Impreza fitment, plus specified Forester applications, but its coverage is narrower than EPAuto's.

Genuine Subaru part 72880FN00A replaces 72880FN100 and is listed for recent Crosstrek and Impreza models, giving owners a current OEM-numbered cabin-filter option. Its vehicle coverage also includes specified Forester versions, with a Japan-built VIN condition for the 2025–2026 Forester fitment.

The genuine Subaru cabin filter is described as removing millions of microscopic pollutants and dust particles, a function relevant to the cabin air system. Its replacement number, 72880FN00A, supersedes 72880FN100, helping identify the listed filter across the covered applications. Fitment includes 2024–2026 Crosstrek and Impreza, plus 2025 Forester non-Wilderness and Japan-built 2025–2026 Forester models whose VIN starts with J. Subaru recommends using the owner’s manual for the replacement schedule.

Skip it if you need a filter for a different model year or Forester configuration; its stated coverage is limited to the listed applications.

A practical OEM-numbered choice for owners of listed recent Crosstrek, Impreza, and qualifying Forester models. Pay particular attention to the Forester Wilderness exclusion and the Japan-built VIN condition for 2025–2026 fitment.

#7

7. HOOTURB Hood Holder

• Material: Plastic
• Weight: 8.53 g
• Material Type: Plastic

Best for: Crosstrek and Impreza hood-rod support.

Why it ranks #7: A replacement hood prop rod holder corresponds to OE 57242FJ000 and is listed for Crosstrek and Impreza models in the stated range.

Heat-resistant, corrosion-resistant plastic is the stated material for this hood prop rod support holder, intended to retain the prop rod on Subaru Crosstrek and Impreza models from 2017–2025. The holder replaces OE reference 57242FJ000 and is described as resistant to aging and compression.

The plastic holder’s stated heat and corrosion resistance addresses conditions around the engine bay, while its anti-aging and compression resistance support continued use of the prop-rod support. HOOTURB lists Crosstrek and Impreza 2017–2025 applications and OE number 57242FJ000, giving buyers both model and reference details to compare. The compact holder is identified as a prop rod support component; the supplied information does not specify an installation method beyond describing installation as simple.

Skip it if you need a hood prop rod holder for another Subaru model or year; the listed application covers only Crosstrek and Impreza 2017–2025.

A focused replacement option for owners of a listed 2017–2025 Crosstrek or Impreza needing the 57242FJ000 prop-rod support. Its stated application does not extend beyond those model lines and years.

#8

8. BIANJIE Hubcap

• Material: Acrylonitrile Butadiene Styrene
• Material Type: Acrylonitrile Butadiene Styrene

Best for: Single Impreza wheel-cover replacement.

Why it ranks #8: This 16-inch snap-on wheel cover is listed for Impreza models and references OE 28811FL010 and 28811FL02A.

A high-tension metal expansion ring and multiple secure clips give this snap-on hubcap its stated retention system for Subaru Impreza 2017–2023. Sized for 16-inch wheels and referencing original numbers 28811FL010 and 28811FL02A, it is intended as an individual replacement cover.

The expansion ring and multi-point clips work together in the stated snap-on retention design, helping hold the cover against the wheel. Its 16-inch size and Impreza 2017–2023 application define the fit boundary, while OE references 28811FL010 and 28811FL02A identify the original covers it is intended to match. The ABS plastic cover is listed in Celestial Silver, providing a replacement for a missing or damaged cover while keeping the task focused on one wheel.

Skip it if you have a different wheel size or an Impreza outside 2017–2023; those applications are not listed for this cover.

This suits an Impreza owner replacing a single 16-inch wheel cover within the stated 2017–2023 range. Its snap-on retention and OE references are useful checks, but the listed wheel size and model years define its fit.

#9

9. Kolya Wheel Trim

• Material: Acrylonitrile Butadiene Styrene (ABS), Plastic
• Material Type: Acrylonitrile Butadiene Styrene (ABS), Plastic

Best for: Matte-black steering-wheel trim.

Why it ranks #9: The matte-black ABS trim covers the original steering-wheel frame rather than replacing it, and lists selected Forester, Outback, and Crosstrek fitment.

A matte-black ABS cover adds a darker finish to the steering-wheel frame and button area on listed Forester, Outback, and Crosstrek models. Because it covers the original part rather than replacing it, this trim is a cosmetic change intended to leave the stated function unaffected.

The ABS plastic construction and matte-black surface provide the listed material and finish for a cover placed over the original steering-wheel frame trim. Kolya lists 2019–2025 Forester and 2018–2025 Outback and Crosstrek fitment, giving owners those model-year ranges a defined application window. The product is explicitly not a replacement part, and the listing says it does not affect function. That distinction makes it suitable for appearance changes, not for replacing damaged underlying components.

Skip it if you need to replace a damaged steering-wheel frame or button component; this product only covers the original part.

This cover fits the appearance-focused buyer with a listed 2019–2025 Forester or 2018–2025 Outback or Crosstrek. It is a trim overlay, so it is not a repair for an underlying steering-wheel component.

#10

10. KoiLuvGo Radio Harness

• Weight: 2.39 oz

Best for: Aftermarket stereo wiring installers.

Why it ranks #10: The harness includes antenna and steering-wheel-control wiring, but the supplied compatibility details are incomplete and span Subaru, Infiniti, and Nissan.

Color-coded PVC-insulated cables paired with ABS plastic connectors give this harness kit an organized connection path for an aftermarket stereo installation. The title identifies Subaru compatibility for 2008–2013 vehicles alongside Infiniti applications, while the kit also includes an antenna adapter and steering-wheel-control wire.

The color-coded cables can help installers distinguish connections during stereo wiring, and the ABS connectors are described as providing secure connections and conductivity. The included antenna adapter and steering-wheel-control wire add components for the listed installation workflow, rather than leaving those items out of the kit. KoiLuvGo identifies compatibility with 2008–2013 Subaru vehicles in the title, but the supplied vehicle list is incomplete, so the listing does not establish every applicable model.

Skip it if you need a confirmed model-by-model Subaru application list; the supplied compatibility information is incomplete.

Consider this kit for an aftermarket stereo project where the antenna adapter and steering-wheel-control wire are relevant. Its Subaru title coverage is 2008–2013, but the available model-level fit details are limited.
